WILLIAM T. DOLE, OF PEABODY, MASSACHUSETTS.

IMPROVEMENT IN CARRlAGE-HUBS.

Specification forming part of Letters Patent No. 121,857, dated December12, 1871.

To all whom it may concern:

Be it known that I, WILLIAM T. DOLE, of Peabody, of the county of Essexand State of Massachusetts, have invented a new and useful Improvementin Carriage-Wheels and Axles; and do hereby declare the same to be fullydescribed in this, my specification, and represented in the accompanyingdrawing making part thereof, of which- Figure l is a side view, Fig. 2 arear end view, Fig. 3 a longitudinal section, and Fig. 4 a front endview of a carriage-wheel, hub, and axle provided with my invention.

In carrying out one part of my said invention, I construct that part ofthe hub designed to sup port the spokes and the journals of the axle asa cylindrical spoke-carrier, A, and two tubular projections, B 0,extended in opposite directions from the ends of such carrier, therebeing a com mon passage, (0, going through the whole to receive thejournal D, and constitute a bearing therefor. These parts A B C are tobe cast or founded together of metal in one piece, the middle one beingmortised radially, as shown at b b b, to receive the spokes. The saidpart A or spoke-carrier is chambered or recessed at each of its ends andabout the parts B G, as shown at d 0. One of these chambers (viz., thatmarked (1) is for the reception of a wooden collar, E, which is fittedconcentrically upon the projection B and driven closely into the chamberd, and is confined to the spoke-carrier by a series of screw-bolts, f,going through the two, and by nuts 9 screwed upon such bolts, the saidnuts being arranged in the opposite chamber 0. The wooden collar servesto make a finish to the hub and to support the guard-ring F of the nutG, which holds the Wheel-hub on the journal of the axle. To the saidaxle there is fixed a dustguard, H, which is a 1101- of its sides ashort distance, and is formed or provided with a clamp-receiver, l,formed and arranged as shown. An arched clamp, m, going around the axleand through the clamp-receix er, and having nuts 10. n screwed on it, asshown, serves not only to confine the wood portion 0 of the axle to themetallic part 19 thereof, but to hold the dustguard firmly in place onthe axle. The journal has a groove, r, formed lengthwise in it along itsupper edge, there being from the rear end of such channel an induct ortube, 8, arranged in the axle and at an obtuse angle of about onehundred and thirty five degrees with its oilgroove, as shown.

By having the induct inclined to the groove in manner as shown atlexileor elastic wire can readily be introduced into the induct and groove andpushed throughout the latter, so as to clear it out preparatory to oilbeing introduced into it through the induct. This little improvement inthe arrangement of the induct is one of great utility and advantage, asit enables a person to be certain that the oil after being introduced bythe induct will freely flow into and throughout the groove of thejournal.

I claim as my invention the followingthat is to say:

1. The metallic cap F, the Wooden cap-holder E, the screw-bolts and nutsf g, and the metallic spoke-carrier A with its projections B O andchambers d c, all arranged essentially as set forth.

2. Thearrangemeut of the dust-guard H (fastened to the axle) with theparts A and G of the hub, in manner as shown and described, so as toform, in appearance, part of the hub.

3. The arrangement of the induct s and groove 7' with the wheel-journaland the dust-guard H, in manner as shown.

4. The dust-guard H, constructed as described, viz., the hollow frustumH, the socketed projection k, and the clamp-receiver 1, arranged as setforth.
